This 1.23ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831679941 or 831679941. Listed at 17 retailers as of October 31, 2026, with prices from €187 to €1,516, a €1,328 spread on the same certified stone. Brilliant Earth lists it at €1,516. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
